07393 779245 Negative Who called me from this phone number?

Calling claiming to be three mobile and that I'm due an upgrade.... Never had a contract with them

Didn’t say anything, call hung up immediately. Called at 11am on a Saturday!!

Claimed to be from my mobile provider. My usual daily scam call trying to save me money. I never do business over the phone ever.

Said they were calling from Amazon and that someone was trying to buy an Apple iphone using my account. They wanted to check if i had made the purchase or wanted to cancel it. Then they said I don’t have an Amazon account and hung up.

Claiming to be 02. Offering 30% discount. I cancelled the call

Claimed to be my Tesco Service Provider. I said "You are not my service provider" and paused. They said "Oh", I said nothing more and waited. After about 10 seconds they hung up without saying anything more. No legitimate call centre uses a personal number or just hangs up once they have spoken to you. They have to speak politely to you.

Silent and then hung up.

Silent then just hung up. Tried calling back then went straight it voicemail Scam

Silent then call ended

Called claiming to be from Three (I'm not with Three) asking if my line was okay and I'm happy with it. I played my usual game of seeing how long I could keep him on. It was me basically saying I kept getting a really annoying noise on the line then every time he spoke I'd just say "There it is now..." Fair play, he persisted for five minutes before getting annoyed.

Scam

Called me 6 times in the last 6 1/2 hours. Scam caller pretending to be my mobile phone provider and offering discounts for "being a loyal customer".

Regarding sky reducing my bills and offering Apple Watch must have called 10 times

Scammer call.

once I answered, a robotic sounding voice simply said ‘goodbye’ and immediately ended the call. what is going on?
